Introduction

Dana presents this publication to aid in maintenance and overhaul of Spicer single reduction drive axles. Instructions contained cover the models listed below. Their design is common, with differences in load capacity. Capacity variations are achieved by combining basic differential carrier assemblies with different axle housings, axle shafts and wheel equipment. The suffix letter "P" in the model number indicates a lube pump is standard. Pump models are equipped with a gerotor pump, designed to provide additional lubrication to the inter-axle differential and related parts.
